Tesla is set to put its Model S all-electric sedan on the market a few months ahead of schedule, with the first customer deliveries taking place next month. Another bit of good news for Tesla and the people who are waiting for their Model S to take up residence in their driveway has surfaced.

Motor Trend reports that the top-of-the-line (85 kWh) Model S is expected to earn a window sticker rating from the EPA showing a 265-mile driving range.

There has been confusion on the driving range for a fully charged Model S, mostly because multiple numbers have been thrown around since the vehicle was first unveiled. The driving range has been at different times said to be 160-miles, 230-miles, and 300-miles depending upon the size of the battery pack installed. Tesla also recently noted that the car was able to achieve a 320-mile driving range on a full charge in the EPA's 2-cycle driving test.

The new 265-mile range for the window sticker is based on the EPA's new five-cycle test. If Tesla is able to land that 265-mile driving range on the EPA's new test, the Model S will be massively superior to other electric vehicles, such as the Nissan Leaf, which was only able to muster a 73-mile driving range on the same test. Granted, the high-end Model S is much more expensive than the Leaf.

The real world driving distance will likely vary significantly, depending on where the vehicle is operated and how heavy the driver's right foot is.

The Model S is also available with smaller 40 kWh or 60 kWh battery packs. The base Model S will sell for $57,400 and range up to $105,400 for higher end versions with an 85 kWh lithium-ion battery. Tesla has 10,000 orders in hand for the new Model S EV.
